I chose the Atlantic Salmon to base this assignment off of.
The kinds of Atlantic Salmon you should consume mainly come from open net farms in Norway, mainly farms in Kvaroy and Selloyvik. There are recommended Atlantic Salmon found over the world that are farmed in Recirculating Aquaculture System facilities. These facilities are more sustainable than open net pens, and have a healthier environment for the fish to grow up and mature in, while having the minimal amount of risk for developing infections and diseases.
However, the kinds of Atlantic Salmon that you should avoid are mainly found in British Columbia, some places in Norway, Scotland, and Chile. This is because the fish are raised in open net pens, which are known to have fish lice, multiple infections floating around, and they also have the possibility of polluting or tainting the water around the pens. With these pens, the fish inside have received vaccines that affect the fish that live in the outside water in that the outside fish develop illnesses that are harboured by the inside fish. The inside fish are immune so it does not affect them, but it is released into the water that the outside fish live in and it hurts their health.
The 2 main types of how these fish are farmed are open net fish farms and RAS (recirculating aquaculture systems).

So would you say salmon farming in BC is sustainable?
With Atlantic Salmon, most of our would be from BC… I don’t think I’ve seen it shipped from Norway.
